  1. 6. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
    Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

  3. 7. Strength Analysis of Deployable Hangar

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Manan Sureshbhai Rudani; Hampus Ring; [2021]
    Keywords : Strength analysis; Hangar; Finite Element Method; Eurocodes; Snow load; Wind load; Ultimate Limit States;

    Abstract : It is of interest to investigate extended usability of Saab’s Deployable Aircraft Maintenance facility(DAM) with respect to Eurocode standards. One of the features of the deployable hangar is that it shouldcomply with the structural strength standards for permanent buildings which requires compliance withEurocodes. READ MORE

  4. 8. Crack growth based FEM with embedded discontinuities

    University essay from KTH/Hållfasthetslära

    Author : David Lindblom; [2021]

  5. 9. The impact of stage casting on shrinkage restraint in concrete walls

    University essay from KTH/Byggteknik och design

    Author : Cindy Amjadi; Justyna Melek; [2020]
    Keywords : Concrete; concrete wall; stage casting; shrinkage restraint; cracking; FEM-Design; Betong; betongvägg; gjutetappindelning; krymptvång; sprickor; FEM-Design;

    Abstract : The most used widely material in the construction and industrial industry is concrete. Concrete is a material that has been used for a long time and will remain to do so. Therefore, it is especially important to obtain knowledge of the material’s properties and how it is affected by various conditions. READ MORE

  6. 10. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE
